Jason Momoa has shared a video on Instagram showing a hair stylist shaving off his signature long, wavy hair. While having his iconic locks shaved off, the Aquaman actor spoke about the importance of eliminating single-use plastics. Momoa, who founded bottled water company Mananalu Water, says he is shaving his head to create awareness for the overuse of plastics. Plastic forks. All that (stuff) just goes into our land, goes into our ocean, Jason Momoa. Momoa has yet to reveal what the final cut looks like. However, he seems to have saved his signature goatee this time, having previously shaved it when he launched Mananalu Water in 2019. The bottled water company aims to put water in aluminum bottles instead of plastic ones.
